Update
Evening sea breeze merger from brunswick ga southward to west side
of jax metro area produced a couple of severe storms with damaging
downburst winds including 51 mph wind gust at the jax airport. The
lightning in the area also produced a loss of jax doppler radar
data, which we are hoping to get restored sometime on Sunday.

Last of evening convection fading and expect quiet conds after
midnight with lingering high clouds overnight with normal muggy
overnight lows in the 70s and some patchy light fog near area that
received rainfall. Widely scattered storms possible again Sunday
afternoon as sea breeze fronts push inland and MAX temps in the
lower to middle 90s inland and upper 80s at the beaches along with
heat indices of 100-105 degrees.

Aviation
Convection has basically ended and expectVFR conds with lingering
convective debris clouds overnight. Some fog possible at jax vqq
due to local rainfall but chances still too low to include at this
time. No convection added to tafs for Sunday afternoon due to
storm chances less than 30 percent at this time.

Marine
Southerly flow around 10-15 knots with seas 2-4 ft and local se
sea breezes expected at the coast.

Climate
Record daily wind gust of 51 mph set at the jax airport for august
18th. Record event report (rerjax) sent with further details.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
